UA Plumbers & Pipefitters Apprenticeship Guide 2025: Everything You Need to Know

The United Association (UA) of Plumbers, Pipefitters, Sprinkler Fitters, and HVAC Service Techs sponsors one of the most comprehensive skilled trades apprenticeships in the country. UA apprentices earn while they learn, receive free classroom training, and emerge as highly skilled journeymen earning $60,000–$120,000+ annually depending on specialization and location. The plumbing and pipefitting trades are facing a critical worker shortage — making now an outstanding time to apply.

What Does "UA" Cover? More Than Just Plumbing

The United Association is broader than most people realize. UA apprenticeship programs include:

• HVAC Service Technicians: Maintenance and repair of commercial HVAC systems

What You Learn in the UA Apprenticeship

The curriculum varies by specialty, but a plumber apprenticeship typically covers:

• Pipe identification, cutting, threading, and joining methods
• Plumbing codes (IPC and local codes)
• Water supply system design and installation
• Drainage, waste, and vent (DWV) systems
• Gas piping installation and pressure testing
• Water heater and boiler installation
• Backflow prevention and cross-connection control
• Green plumbing and water efficiency
• OSHA 10/30 safety certification
• Blueprint reading and estimating

Pipefitting apprenticeships add industrial systems, welding (usually SMAW and TIG), steamfitting, and process piping design.

Pipefitters: The Highest-Paid Specialty

Industrial pipefitters who work on power plants, petrochemical refineries, pharmaceutical plants, and shipyards earn some of the highest wages in the trades. In major industrial markets (Houston, Louisiana Gulf Coast, Midwest refinery corridor), journeyman pipefitters can earn $45–$65/hour plus per diem for travel work. The travel and refinery "turnaround" market pays premium wages for experienced pipefitters willing to travel for short-term projects.

Career Advancement After Journeyman Status

• Journeyman Plumber/Pipefitter: $35–$65/hour; eligible for master's license exam
• Master Plumber: State license to supervise and run projects; $80,000–$120,000+/year
• Foreman/General Foreman: Union leadership of crews; 10–20% above journeyman wage
• Plumbing Contractor: Business owner; no earnings ceiling
